Maserati teases all-electric 2022 GranTurismo prototype

Maserati trotted out an early prototype of the 2022 GranTurismo this week, teasing the all-electric replacement for its long-running luxury coupe. The spy-style photographs were shot around the streets of Modena, near the automaker's Innovation Lab, Maserati said in the announcement accompanying the shots. The previous-generation GranTurismo was in production for 12 years before finally retiring in 2019.  The new GranTurismo and its drop-top counterpart, the GranCabrio, have been in development since 2019, but it wasn't until more recently that Maserati confirmed that the next-gen two-doors would spearhead (trident-head?) the company's electrification push. We expect it to borrow from Maserati's upcoming Folgore powertrain which can be configured with up to three electric motors for both all-wheel drive and torque vectoring.  "Going electric is the next logical step. We are trying to avoid unnecessary air openings and air outlets, in contrast to some of our competitors that seem to depend on them to convey a message," explained Maserati head of design Klaus Busse in a previous interview with Autoblog. "In our case, it's about the purity of the body. We can further purify the car by reducing the amount of air intakes and air outlets, which will help us tell the design story even better." We expect to learn details of the all-electric GranTurismo later this year.  Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

Maserati switching to in-house twin-turbo V6 and turbo four

Automotive News has been able to put some output figures to the two primary engines that will power Maserati's renaissance. Last year the Italian luxury brand sent notice that it would terminate its deal to with Ferrari to use the Maranello-sourced F160 3.0-liter twin-turbo V6 and F154 3.8-liter twin-turbo V8. As new Maserati models appear and current models are overhauled, the brand will begin installing either Maserati's own 3.0-liter twin-turbo V6, or an FCA-sourced 2.0-liter turbocharged four-cylinder. The V6 will greet the world from the middle of the MC20 supercar poised for debut in September, assuming nothing goes worse with the world than it already has. Rumor from Mopar Insiders and Allpar forums is that Maserati began building its V6 based on Alfa Romeo's 690T V6. Alfa Romeo puts the 690T in the Stelvio and Giulia Quadrifoglio, the engine's development having started seven years ago with Ferrari's F154 V8 as its heart. Tuned for speed, peak output could reach 542 horsepower. After making its home in the racy coupe, the V6 will also serve a new midsize Maserati crossover coming next year, as well as the next GranTurismo coupe and GranCabrio convertible. In the crossover, power is apparently limited to no more than 523 horses. In Maserati's new V6, one piece of technology that permits such high output and emissions friendliness is turbulent jet ignition (TJI). German supplier Mahle has been developing the technology for at least 10 years, and put it to use in Ferrari's Formula 1 engine about five years ago, after which Japan's Super GT manufacturers picked it up. Instead of a spark plug igniting fuel directly in the combustion chamber, TJI places the spark plug and an injector nozzle at the top of a "jet ignition pre-chamber assembly." The injector shoots a mist of gasoline into the pre-chamber, the spark plug fires, and the force of ignition in the pre-chamber sprays the combustion through tiny holes at the bottom of the pre-chamber into the cylinder as the piston rises. Mahle says the shorter burn and improved combustion spread means cleaner-burning gas engines that emit fewer emissions.   AN says that the "new V-6 engine will be 'electrified' in some form." It's not clear if that means all versions of the V6 will get some sort of hybrid assistance, or if — as had been thought — there will be a non-hybrid unit.
